Didn't get all contacts from all linked accounts [Android]

Hey guys! Amazing job with this package!

I've just noticed an issue when multiple contacts accounts linked.

When using the FastContacts.getAllContacts() method (package version 3.0.3), I noticed that it only retrieves device contacts and the first linked Gmail account's contacts, even if there are multiple Gmail accounts linked to the Android device.

This issue was reproducible on my device with two Gmail accounts and phone contacts.
